Pilonidal (nest of hair) cysts are foreign body reactions accompanied by chronic inflammation. Current accepted treatments include the traditional conservative treatments or aggressive surgery. However, these modalities exhibit a high rate of disease recurrence, especially in patients with hirsutism; therefore, affected patients often are subjected to repeated surgical interventions. This report describes 5 patients treated with either a diode laser or intense pulsed light (IPL), which produced results leaving the patients recurrence free. Four of 5 patients remained recurrence free for 7 months to more than 36 months; one patient experienced a recurrence after 36 months, which was longer than his previous remission. These results suggest laser and IPL technologies are alternatives to traditional surgical intervention, providing potentially longer disease-free intervals and fewer recurrences.

Objectives: Combining Computed Tomography (CT) intuitive anatomical features with Three-Dimensional (3D) CT multimodal radiomic imaging features to construct a model for assessing the aggressiveness of pancreatic neuroendocrine tumors (pNETs) prior to surgery.
Methods: This study involved 242 patients, randomly assigned to training (170) and validation (72) cohorts. Preoperative CT and 3D CT radiomic features were used to develop a model predicting pNETs aggressiveness.

Introduction: Irreversible electroporation(IRE) has augmented the effects of certain immunotherapies in pancreatic cancer(PDA). Yeast-derived particulate beta-glucan induces trained innate immunity and has successfully reduces murine PC tumor burden. This is a Phase II study to test the hypothesis that IRE may augment beta-glucan induced trained immunity in patients with PDA.

Background: PD-L1 expression in tumors and immune cells is a biomarker for the efficacy of anti-PD-1 antibody (APA) therapy across diverse cancers. Based on the results from the KEYNOTE-048 trial, pembrolizumab monotherapy is indicated for platinum-sensitive recurrent/metastatic head and neck squamous cell carcinoma (R/M-HNSCC) with a positive combined positive score (CPS). Conversely, nivolumab is utilized for platinum-pretreated R/M-HNSCC regardless of the positive tumor proportion score (TPS) following the results of the CheckMate-141; however, its subgroup analysis indicated that TPS-positive population tended to have a relatively high overall response rate and progression-free survival (PFS).

Objectives: We aimed to compare the outcomes of patients with T1-T2N0M0 glottic squamous cell carcinoma who underwent either partial laryngectomy (PL) or radiotherapy (RT).
Methods: A retrospective analysis of 562 patients treated with RT (n = 151) or PL (n = 411) was conducted. The Kaplan-Meier method was used to estimate outcomes.

Background: () infection is a significant risk factor for hepatocellular carcinoma (HCC), yet its underlying mechanisms remain poorly understood. This study aimed to investigate the impact of infection on the serum proteomic and metabolomic profiling of HCC patients, focusing on the potential mechanisms.
Method: A retrospective clinical analysis was conducted on 1121 HCC patients, comparing those with and without infection.
